Publication number: 20090236235Abstract: A water treatment system provides treated or softened water to a point of use by removing a portion of any hardness-causing species contained in water from a point-of-entry coming from a water source, such as municipal water, well water, brackish water and water containing foulants. The water treatment system typically treats the water containing at least some undesirable species before delivering the treated water to a point of use. The water treatment system has a controller for adjusting or regulating at least one operating parameter of the treatment system or a component of the water treatment system to optimize the operation and performance of the system or components of the system. A flow regulator regulates a waste stream flow to drain and can be operated to recirculate fluid through electrode or concentrating compartments of an electrochemical device and can opened and closed intermittently according to a predetermined schedule or based on an operating parameter of the water treatment system.Type: ApplicationFiled: June 2, 2009Publication date: September 24, 2009Applicant: SIEMENS WATER TECHNOLOGIES HOLDING CORP.Inventors: Frederick Wilkins, Evgeniya Freydina, Aytac Sezgi, Reshma Madhusudan, Anil D.

Publication number: 20050103622Abstract: A treatment system provides treated or softened water to a point of use by removing at least a portion of any undesirable species contained in water from a water source. The treatment system can be operated to reduce the likelihood of formation of any scale that can be generated during normal operation of an electrochemical device. The formation of scale in the treatment system, including its wetted components, may be inhibited by reversing or substituting the flowing liquid having hardness-causing species with another liquid having a low tendency to produce scale, such as a low LSI water. Various arrangements of components in the treatment system can be flushed by directing the valves and the pumps of the system to displace liquid having hardness-causing species with a liquid that has little or no tendency to form scale.Type: ApplicationFiled: November 13, 2003Publication date: May 19, 2005Applicant: United States Filter CorporationInventors: Anil Jha, Frederick Wilkins, Evgeniya Freydina, Aytac Sezgi, Reshma Madhusudan
